How to setup nginx to create a sub-domain? - nginx

Question

I have one domain myartistbook.in, which is working fine. I want to create a sub-domain for it named adminpanel.myartistbook.in. The steps I followed are:
Added sub-domain name to /etc/hosts
127.0.0.1 localhost
***.***.***.180 myartistbook
***.***.***.180 adminpanel.myartistbook
edited /etc/nginx/nginx.conf:
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
include /usr/share/nginx/modules/*.conf;
events {
worker_connections 1024;
}
http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
include /etc/nginx/mime.types;
default_type application/octet-stream;
include /etc/nginx/conf.d/*.conf;
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name myartistbook.in www.myartistbook.in;
root /root/krim.com;
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location / {
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
server {
listen 80;
root /root/sites/adminpanel.com;
server_name adminpanel.myartistbook.in www.adminpanel.myartistbook.in;
index index.html;
location / {
try_files $uri $uri/;
}
}
}
Added a file named adminpanel.com inside /etc/nginx/sites-available.
server {
listen 80;
server_name www.adminpanel.myartistbook.in;
server_name ***.***.***.180;
root /root/sites/adminpanel.com;
index index.html;
access_log /var/log/nginx/adminpanel.com.access.log;
error_log /var/log/nginx/adminpanel.com.error.log;
location / {
try_files $uri /index.html =404;
}
}
Linked the above server block into /etc/nginx/sites-enabled
sudo ln -s /etc/nginx/sites-available/adminpanel.com /etc/nginx/sites-enabled/adminpanel.com
Restarted nginx with
sudo service nginx restart
While accessing the site I'm getting error adminpanel.myartistbook.in’s server IP address could not be found.
Am I missing any step?

Answer 1

Together with server-side configurations involving domains and subdomains in server_name, you need to make sure that your DNS records for myartistbook.in are properly configured as well.
Have you added a DNS record to point adminpanel.myartistbook.in to your server? You can either add an A record or a CNAME record for this. Looking at a quick check using whatsmydns.net for adminpanel.myartistbook.in, it seems you missed this step. Please check the documentation of your domain registrar on how to do this.
After adding the records, do a quick check again using whatsmydns.net if your CNAME/A record has taken effect.
In your step 3, modify the server_name to adminpanel.myartistbook.in without the www, unless this is actually your intention to use the whole www.adminpanel.myartistbook.in, which I don't think is the case here because you attempted to access it without the www:
adminpanel.myartistbook.in’s server IP address could not be found.
Also, it's probably good to use a different server {} block when referring to IP addresses as server_name then redirect to the domain/subdomain. However, redirecting from IP Address going to your domain/subdomain may be not be the priority now. Suggest to remove that line in the meantime.
Then run a quick nginx -T to check for errors in your configuration. If the check is successful, reload your nginx web server and try accessing the subdomain again.
Hope that helps!
